Cosmetic compositions

Abstract

A composition is provided. The composition is a water-in-oil emulsion comprising an aqueous phase and an oil phase. The aqueous phase comprises water, one or more humectants, one or more preservatives, one or more preservative boosters, one or more stabilizers and/or one or more pH adjusters. The oil phase comprises one or more solvents, one or more emulsifiers, one or more emollients and/or one or more aesthetic modifiers. Methods of preparing the composition and methods of improving the appearance of skin are also provided.

What is claimed: 
     
       1. A cosmetic composition, comprising:
 (a) an aqueous phase comprising:
 (i) water, 
 (ii) one or more humectants, and 
 (iii) one or more preservatives, preservative boosters and/or stabilizers; and 
 
 (b) an oil phase comprising:
 (i) two solvents selected from the group consisting of diisopropyl adipate and diisopropyl sebacate, diisopropyl adipate and ethyl PG-acetal levulinate, diisopropyl adipate and ethyl glycerin acetal levulinate, and diisopropyl adipate and triethyl citrate, 
 (ii) one or more emulsifiers, and 
 (ii) one or more emollients, and 
 (iv) one or more aesthetic modifiers; 
 
 wherein the composition is a water-in-oil emulsion; and 
 wherein the composition improves the appearance of skin by reducing the appearance of fine lines, wrinkles, and imperfection of skin appearance and texture. 
 
     
     
       2. The composition of  claim 1 , wherein the two solvents are diisopropyl adipate and diisopropyl sebacate. 
     
     
       3. The composition of  claim 1 , wherein the one or more aesthetic modifiers comprise one or more functional fillers and one or more effect pigments. 
     
     
       4. The composition of  claim 3 , wherein the functional fillers are selected from the group consisting of methyl methacrylate crosspolymer, boron nitrile, bismuth oxychloride, and polymethylsilsesquioxane. 
     
     
       5. The composition of  claim 3 , wherein the effect pigments are selected from the group consisting of surface treated mineral substances, surface treated synthetic substances, untreated mineral substances, and untreated synthetic substances. 
     
     
       6. The composition of  claim 5 , wherein the effect pigments are of a singular or multilayer structure coated with titanium dioxide, iron oxides, or a combination thereof. 
     
     
       7. A method of preparing a cosmetic composition, comprising the steps of:
 (a) providing an aqueous phase comprising:
 (i) water, 
 (ii) one or more humectants, and 
 (iii) one or more preservatives, preservative boosters and/or stabilizers; 
 
 (b) providing an oil phase comprising:
 (v) two solvents selected from the group consisting of diisopropyl adipate and diisopropyl sebacate, diisopropyl adipate and ethyl PG-acetal levulinate, diisopropyl adipate and ethyl glycerin acetal levulinate, and diisopropyl adipate and triethyl citrate, 
 (vi) one or more emulsifiers, and 
 (viii) one or more emollients; and 
 (viii) one or more aesthetic modifiers; 
 
 (c) contacting the components of the aqueous phase with the components of the oil phase to form a water-in-oil emulsion. 
 
     
     
       8. A method of improving the appearance of skin in a subject, comprising applying to the skin an effective amount of the composition of  claim 1 . 
     
     
       9. The method of  claim 8 , wherein the improving the appearance of skin comprises reducing the appearance of fine lines, wrinkles, and imperfection of skin appearance and texture.
